摘　　要：质子交换膜燃料电池(Proton Exchange Membrane Fuel Cell, PEMFC)在汽车领域经过近30年的持续突破,基本满足了商业化车用技术要求,进入了示范应用阶段。但成本和寿命仍然是限制PEMFC大规模应用的难题,本文针对影响PEMFC寿命的常见衰减工况之一的高电位工况,归纳分析高电位工况堆电堆相关部件的衰减机理,并从材料优化和系统控制两个方面总结了现有的缓解技术。PEMFC basically meet the technical requirements of commercial vehicles after nearly 30 years of continuous breakthroughs. PEMFC vehicles have been entered the demonstration application stage recently. However, the cost and lifetime are still the problems that limit the large-scale application of PEMFC. In this paper, the degradation mechanism of the related PEMFC components under the high potential condition are summarized and analyzed, which is one of the common attenuation conditions affecting the lifetime of PEMFC. Furthermore, the existing mitigation technologies are summarized from the aspects of material optimization and system control.
